I've tried downloading the PPC version of Core 4 several times to CD-R. Mediacheck shows all but the first .iso pass. Regardless of which mirror I use, the first .iso file always seems to faily the Mediacheck. I'm wishing to dual-partition my PowerBook G4 with OS X and Core 4. For the life of me I cannot understand why one file would fail the Media check from all mirrors. Then, following the instructions, I attempted to run 'sha1sum' to compare the Disc 1 .iso file with the reg from the site; however my terminal in OS X will not find the command 'sha1sum' to compare the two files. Any ideas on what to try next would be appreciated. Also - Is Fedora one of the kernels that will allow for repartitioning during the install process, or should I be reinstalling and repartitioning OS X prior to attempting a dual-partition install? If not, it is my understanding that for a machine running 1 GHz of RAM I should create a swap partition of about 2GB in size and a second partition for Core 4 that is around 10GB and that file type OS X extended is the preferred format. Is this correct? My HD is 80G and I do not anticipate using Fedora for any heavy image storage - mostly documents, email and internet. TIA AB -- Adam Boettiger NOTE: I value your time.
